Title: Hydraulic control valve
IPC: F15B13/08
Filed: 1972-02-22
Abstract: 1386975 Valves HYDRAULIC INDUSTRIES Inc 22 Feb 1972 [2 Nov 1971] 38512/74 Divided out of 1386971 Heading F2V The subject-matter of this Specification is the same as that of the main Specification 1,386,971 but the claims relate to the valves 86, 98 and 91 connected to the return feed lines 18, 19, L2. Valve 86 connects the lines to exhaust and opens when pressure in the lines exceeds a predetermined value. Valve 98 connects the lines to the inlet 16 and is normally closed, but opens when pressure in lines falls below said predetermined pressure, such that said pressure is maintained. Check valves 91 connect the lines to motor ports 27, 28 and open when the pressure in the motor ports falls below said predetermined pressure.

Title: Improvements in or relating to pressure regulators for aircraft breathing systems
Inventor: CLEMENTS HUBERT JOHN TOPHAM
IPC: A62B7/04
Filed: 1963-10-01
Abstract: 1,023,605. Respiratory appliances. WALTER KIDDE CO Ltd. Sept. 25, 1964 [Oct. 1, 1963], No. 38557/63. Heading A5T. Breathing apparatus comprises a combined pressure regulator 2 and jerkin inflation valve 4 having two oxygen inlets 8, 9 (Fig. 2, not shown) for connection with main and emergency oxygen supplies respectively, the jerkin inflation valve being downstream of the regulator and arranged to open when the pressure in the outlet side of the regulator exceeds atmospheric pressure by a predetermined amount. The combined pressure regulator and jerkin inflation valve is secured to the fabric 5 of a jerkin by studs 6. The main oxygen inlet 8 is closed by a valve 81, when disconnected from the main oxygen supply, when the emergency oxygen inlet is used. The main oxygen source supplies, at each inhalation, at lower altitudes a metered quantity of oxygen, which is insufficient to meet a normal demand, and, at higher altitudes a continuous uniform supply. On inhalation, a diaphragm 17, which is exposed on one side to the ambient pressure and on the other side through a passage 19 with the inlet passage 18 to a breathing mask, moves a lever 24<SP>1</SP> to open a valve 27 so that pressure is reduced on the undersurface of a diaphragm 22. The diaphragm 22 then moves to open an oxygen inlet passage 20 so that oxygen flows through passages 21, 21<SP>1</SP> to the mask inlet passage 18. When, at lower altitudes the pressure at the inlet 8 drops, the inspiration valve 31 opens against a spring 32 to supply the remainder of the gas required for inhalation. The inspiration valve is connected by a rod 35 to a piston 36 which is slidable in a cylinder 34. The cylinder has an inlet 38 connected through a part 39 with the main oxygen supply, so that, when the oxygen supply pressure is high, the piston is raised to hold the inspiration valve closed at the beginning of an inhalation at lower altitudes and at higher altitudes. The jerkin inflation valve comprises a valve member 51 supported on one side of a diaphragm 53. The valve member is normally held closed against a magnetic seat 52 and the other side of the diaphragm is exposed to the ambient pressure through a tube 58. The valve member 51 is set to open at an ambient pressure above that at which the oxygen supply source operates to supply oxygen continuously at uniform pressure. When the ambient pressure falls below a predetermined amount, an aneroid capsule 45 closes communication between one side of the diaphragm and the ambient atmosphere, this side of the diaphragm then being maintained at a pressure above the ambient pressure through a passage 40 connected with the oxygen inlet passage 20.

Bi-directional shift register composed of bistable multivibrators having a trigger input, which on receiving a "1" causes the multivibrator to change state, has an input to each trigger applied through either of two three-input AND gates Uv, Ur, the inputs of one AND gate Uv being a clock pulse, a forward shift signal and the output from either of two two-input AND gates Ua2, Ua1 which receive, for one Ua1 the false output of the multivibrator FF receiving the trigger signal and the true output of the preceding multivibrator and for the other, the false output of the preceding multivibrator and the true output of multivibrator FF, the inputs of the other AND gate Ur being a clock pulse, a backward shift signal and the output from either of two input AND gates U1, U2 which receive for U1 the true output of multivibrator FF and the false output of the succeeding multivibrator and for U2 the false output of multivibrator FF and the true output of the succeeding multivibrator. The shift register thus causes shifting in either direction and only enables the appropriate AND gates to supply a trigger signal if the contents of the receiving and sending multivibrators differ.
